HTTP Prompt is an interactive command-line HTTP client featuring autocomplete and syntax highlighting. Download url -> https://github.com/eliangcs/http-prompt – Joe C. Hecht – Google+

To me it looks remarkably similar to https://github.com/jkbrzt/httpie [WayBack] which too is a visual cURL replacement.

I’ve been using cURL but always had a feeling not to its potential basically because the cURL man page [WayBack] is both massive and lacks concrete useful practical examples.
For instance, I knew about the --header and --verbose options (I always use verbose names even though shorter -H and -v exist) to pass a specific header and get verbose output, but the man page basic examples like this by Tader:
curl --header --verbose "X-MyHeader: 123" www.google.comsource: How to send a header using a HTTP request through a curl call? – Stack Overflow [WayBack]
There are some more examples at bropages.org/curl but they’re hardly organised or documented.
So I was really glad I found the below answer [WayBack] by Amith Koujalgi to web services – HTTP POST and GET using cURL in Linux – Stack Overflow.
But first note that recent versions (around 7.22 or higher) of cURL now need to combine the --silent and --show-error (or in short -sS) parameters to suppress progress but show errors: linux – How do I get cURL to not show the progress bar? – Stack Overflow [WayBack]

Cool: [WayBack] Postman offers free (small-project) API developer tools – Open Source Insider.
I’ve used the [Archive.is] Postman – Chrome Web Store for HTTP/HTTPS API testing using various REST services. It’s awesome even though unlike the postmanlabs/postman-chrome-extension-legacy: Postman REST Client Chrome Extension (Legacy Version) it’s not open source any more as it now can run server side and has an API of itself [WayBack].
Get it at [WayBack] Postman | Supercharge your API workflow. Available for Mac OS X, Windows, Linux and Chrome users.

You know the drill: site that limits incoming traffic and has painful VPN. Luckily this time outgoing ssh traffic on port 22 was allowed (because they do SFTP which is SSH File Transfer).
Since I’ve outside Linux boxes and could run a Linux VM there (all Tumbleweed based), this allowed me to do a reverse SSH tunnel. Those are always a bit confusing, but this set of drawings really helps: What’s ssh port forwarding and what’s the difference between ssh local and remote port forwarding – Unix & Linux Stack Exchange [WayBack].
Which brings me to a statement like this:
ssh -o "ExitOnForwardFailure yes" -R :3389:192.168.199.114:3389 -p 33322 93.184.216.34
That didn’t work: a remote machine could not RDP to port 3389, but a local telnet localhost 3389 would. The reason is that by default sshd binds a remote port to the local address only and not the wildcard addres.
So you have to open up the remote config a bit: at least /etc/sshd_config and most likely also your firewall.

Building libssh2 for Windows (Win32/Win64) is a lot harder than I hoped for.
There were no instructions on their website, there was the occasional “use CMake” at #IRC and that was about it.
Of course running just CMake doesn’t work and getting it working involves a lot of non-descriptive error messages, cursing and fruitless searches for them just bumping into “me too” threads not really providing the solution.
I tried building OpenSSL but after building, no `lib` directory appears so I cannot satisfy the dependencies. Not sure what OpenSSL would bring as I could not find any documentation about it either, so I’ll leave it at that.
Might be that `make test` for OpenSSL doesn’t succeed because some vague non-explained error which is odd when doing this on an almost prestine VS 2015 Community Edition VM.
But I’ll take that up with the OpenSSL people one day.
Oh the joy of Open Source…
Below are the steps (below the –more– mark a gist with the most recent version).
The core are these:
These links helped a lot some in the positive, others in the negative sense:

The story isn’t a catch-22, but it is still fun to read:
SSH port is 22. The history of how I (Tatu Ylonen) got it. How to configure it through firewalls and iptables.
It also shows how agile the Internet was back then.

I need to check these against a Chromecast v2 as the below URLs are from a v1 device:
More is possible by using cURL: Chromecast Hacking Has Begun | fiquett.com
sleep 8h; while true; do curl -H "Content-Type: application/json" http://192.168.71.113:8008/apps/YouTube -X POST -d 'v=somevideo'; done

In my case this is about a Philips 42PFL7676H TV, but this likely applies to many Philips TVs from the 2009-2012 era.
According to nmap, these ports are open:
PORT STATE SERVICE REASON VERSION
1925/tcp open unknown syn-ack
2323/tcp open 3d-nfsd? syn-ack
49153/tcp open upnp syn-ack Philips Intel UPnP SDK 1.4 (Philips Smart TV; UPnP 1.0; DLNADOC 1.50)
TCP port 1925 is actually implementing the jointSPACE REST API over HTTP which has some nice documentation (also locally on your TV).
PCremote implements this and is easy to install: just download (or git clone) the html locally or to a web-server and try it, or even easier: browse to the www.netdata.be/tv site. You can even use it on your Raspberry Pi. There is also support for jointSPACE it in agocontrol.
Two nice threads about it from the Philips support forum:
TCP port 2323 seems to be the voodooport which should enable you to do DirectFB Voodoo.
Jean-Marc Harvengt (software engineer at Philips) showed a nice demo (see video below) on using VooDoo. I wish he had published the source code.
TCP port 49153 also hosts an HTTP server. The base URL I could find information about is 192.168.71.115:49153/nmrDescription.xml It seems that nmrDescription.xml has to do with DLNA and upnp.
Later on I found that my brothers 32PFL7675H TV should also support JointSPACE, but that it had to be activated:
AFTER upgrading to the new firmware, jointSPACE NEEDS TO BE ACTIVATED by entering the following digits sequence while watching TV (WatchTV activity): “5646877223”
Source: jointSPACE TVs Developers
Before activation, only port was open 49153. After that, port 2323 was open as well. But the www.netdata.be/tv app doesn’t work on this TV. This does work however: Philips MyRemote – Android Apps on Google Play

For my Link Archive via linux port forwarding to external ip – Google Search:
Need to look at this more closely, but it looks like you need PREROUTING, FORWARD and POSTROUTING and two NATs (DNAT and SNAT), as this graph from Port Forwarding Using iptables – SysTutorials shows:
PACKET IN
|
PREROUTING--[routing]-->--FORWARD-->--POSTROUTING-->--OUT
- nat (dst) | - filter - nat (src)
